Alkylation of carbonyl compounds in water: formation of C-C and C-O bonds in the presence of surfactants
No full textThe formation of C[BOND]C and C[BOND]O bonds by the reaction of enolate intermediates with electrophilic substrates commonly requires strong bases, aprotic solvents and very low temperatures. A way of performing the same reactions with sodium hydroxide at moderate temperatures in aqueous surfactant solutions is presented. Different halides, ketones and surfactants (cationic, zwitterionic and anionic) have been used. The results obtained show that the amount of ketone alkylation is much higher and that the reactions are faster in the presence than in the absence of surfactant aggregates. The hydrolysis of the halide is minimised in the presence of cationic or zwitterionic surfactants
An effective simulation of aqueous micellar aggregates by computational models
No full textWe have computationally studied the interaction modes, localization and orientation of a benzene (Bz) molecule on the surface of micelles formed by cetyltrimethylammonium salts CTAX. Experimental H-1-NMR data on complexation shifts induced by Bz on the polar head hydrogens and on the adjacent methylene hydrogens of CTAX have been interpreted using a computational approach that combines an automatic molecular docking procedure with a calculation module that accounts for NMR complexation shifts due to ring current diamagnetic anisotropy. Three different models were used to reduce the complexity of the micellar system. Computational results, in good agreement with available experimental data, point to a preferential localization of the Bz molecule along the CTAX alkyl tail, about 3.9 angstrom away from the charged nitrogen. The Bz molecular plane is predicted perpendicular to the C-H bonds of the alkyl tail. The good results obtained with the simplest model suggest that it could be used to study more complex systems involving surfactants endowed with molecular recognition or catalytic abilities
Forecast of oil price and consumption in the short term under three scenarios: Parabolic, linear and chaotic behaviour
No full textThe paper examines the evolution of price and consumption of oil in the last decades to construct a relationship between them. Then the work considers three possible scenarios of oil price: parabolic, linear and chaotic behaviour, to predict the evolution of price and consumption of oil up to December 2003.

Perspectives on tissue adaptation related to allostatic load: Scoping review and integrative hypothesis with a focus on osteopathic palpation
No full textIntroduction: Osteopathic care may support an individual's adaptive capacity, including allostatic regulation and tissue changes in both health and disease. The palpatory findings which osteopaths claim are related to tissue changes may be linked to allostatic load. However, this putative link has not been formally investigated.
Methods: We conducted a scoping review to critically appraise the relevant literature on the relationship between allostatic processes and tissue alterations. This review evaluates the use and relevance of palpatory findings in osteopathic care. We searched on PubMed, EMBASE, Cochrane library for research exploring the links between tissue adaptation, allostasis and osteopathic palpatory findings (OPF).
Results: Recent studies provide insights into the role of allostatic regulation on body systems' responses related to tissue alterations. These results provide new insights into the relevance of OPF to clinical practice. Discussion: We build upon the findings of our review to propose a putative model for OPF in clinical practice.
Conclusion: Although the clinical phenomena associated with OPF may be biologically plausible, it lacks the necessary underpinning research evidence. Arguably, the classical focus on the diagnosis of palpable tissue changes fails to integrate biological, social and neuropsychological aspects such as stress responses. Tissue alterations related to stress and allostatic load markers have been less studied. Tissue changes involved in the adaptive process may be useful to practitioners in the field of manual therapy, particularly in osteopathy. We propose that OPF are one of the multidimensional aspects that may inform osteopathic decision-making. However, they should be considered within a biopsychosocial perspective and taking into account concepts of allostatic load and regulation
Patent Foramen Ovale as Possible Cause of Sudden Sensorineural Hearing Loss: A Case Report
No full text<b><i>Objective:</i></b> To present a case of sudden sensorineural hearing loss (SSNHL) and the related diagnostic workup. <b><i>Clinical Presentation and Intervention:</i></b> A 54-year-old man presented with a unilateral SSNHL episode and vertigo. A severe patent foramen ovale (PFO) that included a complete ear nose and throat, audiological, and neurological examination was discovered during the diagnostic workup. Audiometry, blood, and serological tests were performed. Magnetic resonance imaging and color Doppler echography of the supra-aortic trunks and lower limbs were carried out. Finally, transthoracic followed by transesophageal echocardiography and transcranial Doppler were performed in order to confirm the diagnosis of PFO. Medical therapy with systemic steroid and antiplatelet drugs was administered. <b><i>Conclusions:</i></b> This case showed a small PFO associated with an aneurysmatic interatrial septum. The PFO and paradoxical thromboembolism could be involved in the pathogenesis of SSNHL.</jats:p
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Effect of Continuous Touch on Brain Functional Connectivity Is Modified by the Operator’s Tactile Attention
No full textTouch has been always regarded as a powerful communication channel playing a key role in governing our emotional wellbeing and possibly perception of self. Several studies demonstrated that the stimulation of C-tactile afferent fibers, essential neuroanatomical elements of affective touch, activates specific brain areas and the activation pattern is influenced by subject’s attention. However, no research has investigated how the cognitive status of who is administering the touch produces changes in brain functional connectivity of touched subjects. In this functional magnetic resonance imaging (fMRI) study, we investigated brain connectivity while subjects were receiving a static touch by an operator engaged in either a tactile attention or auditory attention task. This randomized-controlled single-blinded study enrolled 40 healthy right-handed adults and randomly assigned to either the operator tactile attention (OTA) or the operator auditory attention (OAA) group. During the five fMRI resting-state runs, the touch was delivered while the operator focused his attention either: (i) on the tactile perception from his hands (OTA group); or (ii) on a repeated auditory stimulus (OAA group). Functional connectivity analysis revealed that prolonged sustained static touch applied by an operator engaged with focused tactile attention produced a significant increase of anticorrelation between posterior cingulate cortex (PCC-seed) and right insula (INS) as well as right inferior-frontal gyrus but these functional connectivity changes are markedly different only after 15 min of touching across the OTA and OAA conditions. Interestingly, data also showed anticorrelation between PCC and left INS with a distinct pattern over time. Indeed, the PCC-left INS anticorrelation is showed to start and end earlier compared to that of PCC-right INS. Taken together, the results of this study showed that if a particular cognitive status of the operator is sustained over time, it is able to elicit significant effects on the subjects’ functional connectivity patterns involving cortical areas processing the interoceptive and attentional value of touch
